鋼波紋涵管的(de)很(hen)多選(xuan)用(yong)加(jia)快了項目施工進度,路基完(wan)工至(zhi)今,高填(tian)土路段均未(wei)產生沉降,路基安穩,涵洞結構未(wei)產生較大(da)變形,很(hen)好(hao)的(de)習慣了地(di)質條件(jian),排水順(shun)利。該結構的(de)應用(yong)有效的(de)處理了在填(tian)方路基上及地(di)基承載力較低路段構筑長涵洞引起不均勻沉降的(de)問(wen)題,與(yu)鋼(gang)筋混(hun)凝土結構比(bi)較。

考慮以上要素,規劃(hua)選用壩式路(lu)(lu)堤方(fang)式填(tian)筑路(lu)(lu)基,設置(zhi)(zhi)高位涵(han)。涵(han)洞(dong)進(jin)口側(ce)邊(bian)坡(po)(po)(po)鋪設復合土工膜,以避(bi)免水(shui)流(liu)下滲穿透路(lu)(lu)基,并在其上設置(zhi)(zhi)護坡(po)(po)(po),減小水(shui)流(liu)對路(lu)(lu)基邊(bian)坡(po)(po)(po)的直接沖刷,匯水(shui)在涵(han)洞(dong)進(jin)口側(ce)溝道內進(jin)行(xing)淤(yu)積(ji)沉沙(sha)后經過排(pai)水(shui)涵(han)排(pai)離路(lu)(lu)基。
不論從施(shi)工(gong)工(gong)期(qi)、施(shi)工(gong)難度、施(shi)工(gong)質量及環境保(bao)護(hu)方(fang)面都具有不行比(bi)較的。因此,鋼波紋(wen)涵(han)管(guan)(guan)的推廣應用在黃土區域公(gong)路(lu)建(jian)設(she)中有著廣闊(kuo)的前景。鋼波紋(wen)涵(han)管(guan)(guan)具有管(guan)(guan)節薄(bo),重量輕,便于運輸(shu)寄存,施(shi)工(gong)工(gong)藝簡略,現場安(an)裝便利,處理北方(fang)冰冷區域對橋梁和管(guan)(guan)涵(han)的結構損(sun)壞問題,組(zu)裝快速(su),工(gong)期(qi)短(duan)等長處。
No matter from the aspects of construction period, construction difficulty, construction quality and environmental protection. Therefore, the popularization and application of steel corrugated culvert pipe has broad prospects in highway construction in loess area. The steel corrugated culvert pipe has the advantages of thin pipe joint, light weight, convenient transportation and storage, simple construction process, convenient on-site installation, handling the structural damage of bridges and pipe culverts in the cold area in the north, fast assembly and short construction period.

為避免鋼波紋(wen)涵(han)管(guan)銹蝕,波紋(wen)管(guan)節出廠前表里外表和緊固(gu)銜接螺栓,進(jin)行了熱浸鍍(du)鋅(xin)處理,鍍(du)鋅(xin)層(ceng)厚(hou)(hou)度≥63μm,平均鍍(du)鋅(xin)層(ceng)厚(hou)(hou)度84μm;施工(gong)安裝(zhuang)時增涂瀝(li)青(qing)涂層(ceng),其規劃運用(yong)年限100年。沿線跨溝位置路基填土高度48米,在溝底設涵(han),涵(han)長將達到(dao)200多米。
由于涵身較長,管節較多,溝底縱坡較大,如果選用混凝土板涵,因高填土原因很簡略造成管節的不均勻沉降及涵管裂縫,且對根底處理要求較高,一起蓋板涵施工工期較長,涵洞損壞后維修困難。而鋼波紋涵管分片重量輕,組裝簡便,施工工期短,安裝后整體性及連續性較好,力學性能優。//hanihanbj.com/
